Cutting List

Using your chosen dimensions, create a cutting list to ensure you have the correct pieces before assembly. The following list assumes a bench that is 60" long, 18" deep, and 18" tall with a backrest consisting of four 1" x 6" slats:

Part Quantity Dimension
Legs (4x4) 4 18" L x 3.5" W
Seat supports (2x4) 3 60" L x 1.5" H
Backrest slats (1x6) 4 20" L x 5.5" W
Backrest supports (2x4) 4 18" L x 1.5" H

Assembling the Bench

Now that you have your cut list and materials, it's time to start building your DIY outdoor bench with back. Begin by assembling the legs and seat supports to create the bench's frame.

AD

Attach the seat supports to the legs using exterior screws and wood glue. Drill pilot holes to prevent the wood from splitting. Ensure the frame is square by measuring diagonally from corner to corner and adjusting as needed.

Adding the Seat Slats

Cut 1x6 boards to fit evenly spaced across the seat supports. Attach each slat using pocket holes or from underneath to create a clean, finished look. Ensure the slats are level and evenly spaced.

Before attaching the backrest supports and slats, decide whether you want your bench backrest to be removable or fixed. If you choose a removable backrest, install hinges on the backrest supports and create corresponding cuts on the bench's front supports to accommodate the backrest when folded.

Attaching the Backrest

If you opted for a fixed backrest, attach the backrest supports to the bench frame using screws and wood glue. Ensure they are plumb and level. Cut 1x6 slats to fit between the backrest supports, spacing them evenly apart.

Attach each slat to the supports using screws or pocket holes. If you prefer a solid backrest, construct it separately using 1/2" plywood or oriented strand board (OSB), and attach it to the backrest supports using screws or hinges, depending on your preference for removable or fixed.

Once the main structure of your DIY outdoor bench with back is complete, fill any screw holes with wood filler. Allow the filler to dry, then sand the surface smooth. Apply exterior paint or sealant to protect your bench from the elements.

Consider adding decorative elements, such as routed edges or carved details, to enhance the appearance of your bench. Personalize it with your favorite stain color or metallic accents to complement your outdoor space.

Your newly constructed DIY outdoor bench with backrest is now ready to provide comfort and style to your patio, deck, or garden. Invite friends and family over to enjoy the fruits of your labor, and look forward to many happy moments shared on your handmade bench.

Embrace the satisfaction of creating something functional and beautiful with your own hands. As you relax on your DIY outdoor bench with back, remember the journey that led to this delightful addition to your home. Happy building, and enjoy the surrounding nature!
